A car bomb has reportedly killed one person and wounded around 30 others in Turkey’s south-eastern city of Diyarbakır.

The attack followed the overnight arrests of 11 lawmakers from the Peoples’ Democratic party (HDP), whose base is largely drawn from Kurds in the region, as well as leftists and progressives throughout Turkey.

The provincial governor’s office said a car bomb went off around 8am on Friday. The office said in a written statement that Kurdistan Workers party (PKK) militants were believed responsible.

It was not immediately clear what caused the blast in the Baglar district but the explosion resounded through the city and ambulances rushed to the scene.
